Abstract:
The present invention refers to housing electronic equipment in an enclosure (1) comprising at least a roof element, two side wall elements (2-7) and two end wall elements (8, 9). At least one of the side wall elements (2-7) comprise a locking device (15) for fastening the side wall element (2-7) to an end wall element (8, 9). The present invention also refers to a method for providing an enclosure for electronic equipment in a space inside an existing building and to a housing for enclosing electronic equipment. The modular structure may be used to house a radio or mobile telephone system base station as well as other electronic equipment.
Abstract:
A communication system is adapted to accommodate changes to bandwidth demand through the use of communiucation interface modules, such as radio modules (121-124), are coupled to a communication signal processor, such as a multi-port modem (110), in order to serve an initial bandwidth demand. Thereafter, additional communication signal processors may be added, being coupled to one or more of the communication interface modules (121-124) decoupled from the initially deployed communication signal processor (110), to serve an increased bandwidth demand. Preferably, an expansion chassis architecture is used to accomodatea number of communication signal processors atleast equivalent to the number of communication information interfaces of the plurality. In preferred embodiments, the communication interface modules operate upon different channels, such as radio frequency channels, although coupling to the communication signal processor upon a same channel, sucha as a common intermediate frequency channel.
Abstract:
The invention concerns a distributed communications system. In particular it concerns a modular system which includes one or more exchange units for installation in a rack at a telephone exchange. Each exchange unit has an exchange line interface, one or more optical fibre bearer cards and one or more service cards to support services to one or more remote units. The system also includes one or more remote units. Each remote unit is enclosed in a sealed housing for installation in a pit or manhole, and has an optical bearer card and remote service cards to provide customer services. The exchange unit is connected to a series of the remote units by a series of optical fibre links which extend between an optical fibre bearer card in each unit. The service cards associated with each optical fibre bearer card in the exchange unit are matched to the service cards of the remote units which are connected in the series to that optical fibre bearer card in the exchange unit.

Abstract:
PURPOSE: A mobile communication relay screwing automatic check solution is provided to help an operator in easily checking whether a screw is fastened or not with the naked eye when assembling a module of a mobile communication relay. CONSTITUTION: A light emitting diode (LED) (301), resistance, and a rolled switch (302) help an operator in easily checking a screw with the naked eye which does not fastened by a mistake of the operator in the assembly of a mobile communication relay. The rolled switch corresponding to the position of each fastening screw (303) is arranged. The fastened LED is turned on if the operator puts an automatic test board on a product to be tested and presses it. The LED of the position of an unfastened screw is turned off. The operator easily rapidly checks whether the fastening screw is fastened or not with the naked eye.
Abstract:
A communication relay apparatus in which functional blocks are integrally formed is provided to arrange each functional block on one substrate, thereby removing a connection wire and improving heat discharging performance. In a substrate(110), a functional block(a~g) performing each function of a communication relay apparatus is integrally mounted. A lower heat discharging plate(100) is adhered to a lower part of the substrate. The lower heat discharging plate performs a heat discharging function. In an upper heat discharging plate(200) is the top of the substrate. The upper heat discharging plate is combined with the lower heat discharging plate. Functional block insertion grooves(A~G) are formed at each location corresponding to the functional block in the upper heat discharging plate. In the upper heat discharging plate, an upper heat discharging fin(201) is formed in an opposite external side to a side contacting with the substrate.
Abstract:
PURPOSE: A vibration and impact absorption apparatus of a communication base terminal is provided to safely protect the electronic apparatus of various circuit boards by absorbing vibrations. CONSTITUTION: A communication base station terminal(100) receives horizontal force from the direction of an arrow(X) according to earthquake or external impact. The wrinkled unit of a wrinkled enclosure(10) is horizontally converted for absorbing a part of the whole impact energy. The lateral movement of the wrinkled enclosure is generated. Damping rubber is horizontally converted for absorbing a part of the whole impact energy. The other impact energy is absorbed by the both-end hinge movement of a hinge bolt(16).
